“…It has been measured by means of MRI that both the right and the left atriums become proportionally larger with endurance training in female athletes (15). This is consistent with the symmetrical/proportional remodelling of the heart to the voluminous exercise training where all chambers of the heart are affected to similar extent.…”

Introduction: Exercise training, besides many health benefits, may result in cardiac remodelling which is dependent on the type and amount of exercise performed. It is not clear, however, whether significant adaptation in cardiac structure is possible in females undergoing resistance type of exercise training. Rigorous high volume training of most muscle groups emphasising resistance exercises are being undertaken by athletes of some aesthetic sports such as female fitness (light bodybuilding). The impact of this type of training on cardiac adaptation has not been investigated until now. The aim of the current study was to disclose the effect of high volume resistance training on cardiac structure and function. Methods: 11 top-level female fitness athletes and 20 sedentary age-matched controls were recruited to undergo two-dimensional echocardiography. Results: Cardiac structure did not differ between elite female fitness athletes and controls (p > 0.05), and fitness athletes had a tendency for a smaller (p = 0.07) left ventricular (LV) mass indexed to lean body mass. Doppler diastolic function index (E/A ratio) and LV ejection fraction were similar between the groups (p > 0.05). Conclusions: Elite female fitness athletes have normal cardiac size and function that do not differ from matched sedentary controls. Consequently, as high volume resistance training has no easily observable effect on adaptation of cardiac structure, when cardiac hypertrophy is present in young resistance-trained lean female, other reasons such as inherited cardiac disease are to be considered carefully.

“…On the other hand, endurance and non-endurance training induce different morphological adaptation due to different impact on cardiac pressure and volume load (12,13,15,25,27). Endurance training tends to cause eccentric whereas strength-power training concentric left ventricle hypertrophy (1,13).…”

“…In this study, we demonstrated that changes in biatrial size can be observed after 16 weeks of intensive training in highly trained female athletes with previous training experience, suggesting that atrial remodeling can be observed not only in men but also in women practicing sports at a high level. A recent study by Mosén and Steding-Ehrenborg, 40 aiming to compare atrial volumes obtained in male and female athletes directly, reported that atrial adjustment to training is more modest in women. Our study aimed to investigate the traininginduced biatrial remodeling in women primarily, and a direct comparison between male and female athletes was beyond the scope of the present study.…”

2; P<0.001) and right atrial volume index (15.66±3.09 versus 20.47±4.82 mL/m 2 ; P<0.001) significantly increased after training in female athletes. Left atrial global peak atrial longitudinal strain and peak atrial contraction strain significantly decreased after training in female athletes (43.9±9.5% versus 39.8±6.5%; P<0.05 and 15.5±4.0% versus 13.9±4.0%; P<0.05, respectively). Right atrial peak atrial longitudinal strain and peak atrial contraction strain showed a similar, although non-significant decrease (42.8±10.6% versus 39.3±8.3%; 15.6±5.6% versus 13.1±6.1%, respectively). Neither biventricular E/e′ ratio nor biatrial stiffness changed after training, suggesting that biatrial remodeling occurs in a model of volume rather than pressure overload. Conclusions-Exercise is able to induce biatrial morphological and functional changes in female athletes. Biatrial enlargement, with normal filling pressures and low atrial stiffness, is a typical feature of the heart of female athletes. These findings should be interpreted as physiological adaptations to exercise and should be considered in the differential diagnosis with cardiomyopathies. (Circ Cardiovasc Imaging. 2014;7:222-229.)

“…Furthermore, THV, and ventricular and atrial volumes in athletes were comparable to what has been shown in cardiac MRI studies of young athletes (Steding et al . ; Mosen & Steding‐Ehrenborg, ). When volumes where normalized to THV there were no differences between groups, which confirms that after lifelong endurance training, athletes’ heart are physiologically enlarged with all four chambers having adapted in a balanced way.…”

“…Left and right atrial maximal volumes were defined as the largest volume just before the start of diastolic filling of the ventricles. Volumes were measured in short‐axis images using planimetry and the endocardial borders of the atria were manually defined as previously described (Mosen & Steding‐Ehrenborg, ). Left and right ventricular end‐diastolic and end‐systolic volumes (EDV, ESV) and left ventricular mass (LVM) were measured in short‐axis images, manually defining endocardial and epicardial borders of the ventricular myocardium.…”

Key pointsr Ageing has negative effects on cardiac function. r Endurance training in young subjects is known to improve cardiac function and the ability to deliver blood to exercising tissue.r This study shows that lifelong endurance training maintains cardiac pumping function at a level similar to sedentary young subjects and by the same mechanisms.r Healthy untrained elderly subjects have maintained cardiac pumping function but use compensatory mechanisms similar to what is seen in patients with heart failure.r Healthy ageing should include regular physical activity to maintain cardiac function.Abstract Age-related decline in cardiac function can be prevented or postponed by lifelong endurance training. However, effects of normal ageing as well as of lifelong endurance exercise on longitudinal and radial contribution to stroke volume are unknown. The aim of this study was to determine resting longitudinal and radial pumping in elderly athletes, sedentary elderly and young sedentary subjects. Furthermore, we aimed to investigate determinants of maximal cardiac output in elderly. Eight elderly athletes (63 ± 4 years), seven elderly sedentary (66 ± 4 years) and ten young sedentary subjects (29 ± 4 years) underwent cardiac magnetic resonance imaging. All subjects underwent maximal exercise testing and for elderly subjects maximal cardiac output during cycling was determined using a dye dilution technique. Longitudinal and radial contribution to stroke volume did not differ between groups (longitudinal left ventricle (LV) 52-65%, P = 0.12, right ventricle (RV) 77-87%, P = 0.16, radial 7.9-8.6%, P = 1.0). Left ventricular atrioventricular plane displacement (LVAVPD) was higher in elderly athletes and young sedentary compared with elderly sedentary subjects (14 ± 3, 15 ± 2 and 11 ± 1 mm, respectively, P < 0.05). There was no difference between groups for RVAVPD (P = 0.2). LVAVPD was an independent predictor of maximal cardiac output (R 2 = 0.61, P < 0.01, β = 0.78). Longitudinal and radial contributions to stroke volume did not differ between groups. However, how longitudinal pumping was achieved differed; elderly athletes and young sedentary subjects showed similar AVPD whereas this was significantly lower in elderly sedentary subjects. Elderly sedentary subjects achieved longitudinal pumping through increased short-axis area of the ventricle. Large AVPD was a determinant of maximal cardiac output and exercise capacity.
